DUMPlNG-CONVEYER.

SPEOIFIOATION forming part of Letters Patent No. 745,183, dated November 24, 1903.

Application filed April 14, 1903. Serial No. 152,563. (No model.)

To all whom, it may concern.-

Be it known that I, FRANCIS HEAD, a citizen of the'United States, residing in Philadelphia,Pennsylvania, have invented certain Im provements in Dumping-Oonveyers, of which the following is a specification.

My invention relates to certain improvements in mechanism for conveying material of various kinds from one locality to another; and it consists more particularly of an improved elevator for raising material to a predetermined point and then discharging the same. I

The obj ectof the invention is to provide an elevating-conveyer which shall have a receptacle maintained in a position to receive and hold material except at the end or in the present instance the top of its run, at which point it shall automatically dump or discharge said matter. This object I obtain as hereinafter set forth, reference being had to the accompanying drawings, in which Figures 1 and 2 are side elevations of myimproved conveyer, showing the bucket or receptacle in its normal and in its dumping position, respectively. Fig. 3 is an end elevation of a conveyer with its receptacle, &c., said receptacle being in the same position as that illustrated in Fig. 2. Fig. 4 is a side elevation of the conveyenplatform, showing also the receptacle andrthe means for supporting the same on said platform; and Fig. 5 is an end elevation of the platform and the receptacle, further illustrating the detail construction of these parts.

In the above drawings, A is a platform or framework having fixed to it two standards or uprights a, united across their tops by a horizontallyplaced beam at, to which is shackled a rope or cable a leading over a shaft (1. to a suitable hoisting mechanism. This shaft and the method of supporting the same from a suitable framework a is well known to the art and does not require further description.

Rigidly secured to the platform is a channel-shaped piece B, having at its extremities upwardly-projecting lugs I), provided with bearings for a pin or bolt b. Hinged to the platform A by means of said pins are standards or connecting-rods 17 whose upper ends are in turn constructed to receive a horizontal shaft b said ends having in the present instance removable caps 6 the object of such construction being to reduce to a minimum the labor of removing or replacing theshaft b and its attached parts. Said shaft extends beyond or outside of the bearings and the standards 6 being provided at its ends with rollers 19 for a purpose hereinafterdescribed.

A portion of the shaft 17 between the standards b is suitably shaped to receive and support a bucket or receptacle 0, which in the present instance is shown as rigidly held to it by means of a series of bolts 0. The receptacle may be described as having two sides, each extending upwardly from its bottom edge at an angle to each other and provided with ends in the shape of circular sectors. Extending across the top of the receptacle and through its ends is a bar or rod .0,

held from longitudinal movement by means of nuts 0 screwed upon it and pressing against the inside surface of said ends. The shaft itself extends parallel to the shaft 12 and like it has projecting end portions provided with rollers 0 In order that the receptacle may remain in an upright position under normal conditions, I provide guides D at each side thereof, each consisting of two angles d and d, placed parallel to one another, as shown, and held to a supporting structure, (shoWnatd andcZ The distancebetweenthe upwardly-projecting parallel portions of the angles (1 and dis made slightly greater than the diameter of the rollers b and 0 so that these may run in said guides without undue friction or bearing against their sides. The up per portion of the guides D is curved at (1 as illustrated in Figs. 1 and 2, so as to change their direction to an extent depending upon the shape of the bucket and the point at which it is desired its contents shall be discharged. A framework E is preferablyused as an anchorage for the ends of the curved portions of the guides and as a support forthe structure comprised by the-parts d and (i In operation the receptacle 0, which in the present instance is particularly designed to convey ashes, is filled while in the position shown in Fig. 1, and the hoisting mechanism through the agency of the cable a raises the platform supportingsaid receptacle,thislatter being retained in its upright position by means of the two sets of rollers 19 and 0 As the receptacle nears the top of its run the rollers c will enter the curved portions of the guides D and will tip the bucket out of its normal position, swinging it upon the shaft b as an axis. As said rollers pass farther around the curved portion of the guides the second set of rollers 5 enter said portion and further tip the receptacle (3, since the standards I) will hinge or turn on the bolts b, until finally the bucket assumes the position shown in Fig. 2 and discharges its contents. The cable a is then slacked off, and the weight of the platform A, with the uprights a and the beam a, causes the whole device to descend, the rollers b and 0 following each other out of the curved portion of the guides into the straight part thereof, so as to right the receptacle.

It will be seen from the above that by hinging the conveying-receptacle to a frame at tached to the hoisting mechanism and providing a device by which said receptacle is automatically caused to discharge its contents at the desired point of its path of motion I am enabled to do away with the necessity of providing manual labor for the purpose of dumping the receptacle, thus not only securing a very material economy in the cost of operation of the device, but also lessening the probability of personal injury to the operator.

I claim as my invention 1. The combination in an elevator, of a carrier, means for raising and lowering the same, a standard on the carrier, a bucket movably supported on the standard, and means for tipping the bucket to discharge the contents at a predetermined point in the path of motion of said carrier, substantially as described.

2. In a conveyer, the combination of a carrier, a pair of upwardly-projecting standards thereon, a receptacle movably connected to the standards, means for normally retaining said receptacle in an upright position, means for moving the carrier and its receptacle and means for causing'the receptacle to discharge its contents at any desired point, substantially as described.

3. The combination of a carrier, a bucket, means for supporting the bucket on the carrier, said means being movably connected both to the carrier and to the bucket, with means for raising the carrier and means for tipping the bucket at a predetermined point, substantially as described.

4. The combination of the receptacle, means for moving the same along a predetermined path, a standard movably connected to the receptacle and to said moving means, a device for normally retaining said receptacle in an upright position, means along said path of motion for engaging the receptacle and cansing it to discharge its contents at a predetermined point, with a projection on. the receptacle and a second projection adjacent to the point of connection between the standard and l the receptacle, said projections coacting with the means for keeping the receptacle in an upright position, substantially as described.

5. The combination of a carrier, a standard hinged thereto, a receptacle hinged to the standard, means for normally retaining the receptacle in an upright position, means for moving the carrier and the receptacle along a predetermined path, and means for causing said receptacle to discharge its contents at a predetermined point along said path, substantially as described.

6. The combination of a carrier, elevating mechanism attached thereto, a standard hinged to said carrier, a receptacle attached to said standard, a guide for normally retaining the receptacle in an upright position, said guide including a structure placed to cause motion to the receptacle at a definite point of its line of motion to cause it to discharge its contents, with means carried by the standard at a point other than that at which it is connected to the carrier and other means on the receptacle, for coactin g with said guide to retain the whole in operative position, substantially as described.

7. The combination of a carrier, elevating mechanism attached thereto, a standard hinged to the carrier, a receptacle hinged to the standard, projections from the standard and from the receptacle, a guide engaging said projections to retain the receptacle in its upright position, a portion of said guide being constructed to cause said receptacle to turn on its hinged support and thereby discharge its contents, substantially as described.

8. The combination of a carrier, a standard hinged thereto, a receptacle hinged to said standard, a projection from the standard and a projection from the bucket relatively distant from its point of support, a guide engaging both of said projections and normally retaining the receptacle in an upright position, said guide having an inclined portion whereby the receptacle is caused to discharge its contents when its projections enter said part of the guide, substantially as described.

9. The combination of a carrier, two standards hinged thereto, a bar rotatably carried by said standards, a receptacle fixed to said bar, a second bar substantially parallel to the first and fixed to the bucket relatively distant from said supporting-bar, guides engaging both of said bars and normally retaining the receptacle in an upright position, said guides having portions constructed to incline the receptacle and cause it to discharge its contents, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRANCIS HEAD.
